You're pretty smart..i was thinking some sort of chase through a set terrain whather it be forrests or caves and capturing the people or person fleeing without using lethal force. it will aid in resourcefulness (with the use of terrain and items e.t.c.) and improve teamwork for both teams . you don't want to be caught whilst fleeing just as much as you don't want to let fleeing ninja get away ... it would be two useful skills in one training session
and we could alternate afterwards
How old r you anyway??
